MORRIS W. POOL, OF BROOKLYN, NEW YORK, ASSIGNOR TO REMINGTON TYPE- WRITER COMPANY, OF ILION, NEW YORK, A CORPORATION OF NEW YORK.

TYPEWRITING MACHINE.

Application filed September 30, 1922. Serial No. 591,571.

To all whom it may concern:

Be it known that I, MORRIS W. Poon, citizen of the United States, and resident of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

The present invention relates to paper controlling mechanism for typewriting machines, and has for its general object the provision of improved collating and feeding mechanism for the work sheets of such machines. A specific object of the present invention is to adapt certain features of the invention disclosed in my prior application, Serial No. 17O,81-8,. filed May 19, 1921., to a front strike typewriting machine, such as the No. 10 Remington typewriter.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings,

Figure 1 is a fragmentary front to rear vertical sectional view of the carriage of a No. 10 Remington machine, showing one form of my invention applied thereto.

Figure 2 is a fragmentary sectional view showing some of the parts of Figure 1 in abnormal positions.

Figure 3 is a fragmentary front elevation r of the parts shown in Fig. 1, the end bars of the platen frame, however, being in section.

Figures. 4 and 5 are enlarged sectional views taken respectively on the section lines 11 and 2-2 of Fig. 3 and looking downward.

Figure 6 is a fragmentary end view, partly in section, of a modification.

Figure 7 is a fragmentary eud'view of another modified construction.

Figure 8 is a vertical sectional view, taken on the section line 33 in Fig. 7, and lool ing forward in the direction of the arrows at said line.

Figures 9 and 10 are enlarged sectional views of the opposite ends of the clamping device shown in Figures 7 and 8.

Figure 11 is a fragmentary view illustratmg the latch for said clamping device in inoperative position.

Figure 12 is a perspective view of one of the roller bearings for a clamp carrying band.

Referring first to the construction disclosed in Figs. 1 to 5, arranged above the top plate 1 are fixed track-bars 2 and 3, which co-operate through anti-friction rollers 4; with the front and rear bars 5 and (i of a carriage truck, which further includes connecting end bars 7. Shifta-bly supported on said truck by devices comprising links 8, is a platen frame or carrier comprising end bars 9, rearward extensions whereof are connected by a cross rod or bar 10. Rotatively mounted on the platen carrier is a round or cylindrical platen 11, with the front face whereof co-operate printing instrumentalities or type bars 12. .The platen frame and platen are shiftable up and down on the truck 5, 6, 7, to change case as is usual in the Remington typewriting machine. (lo-operating with the platen at its under side are main and, secondary feed rollers numbered respectively 13 and 14, and a curved paper apron or deflector 15. The feed rollers are releasableby the usual devices comprising a release rock shaft 16 which bears rotatively in the end bars 9 in rear of the platen. A release key or handle 17 secured to the lefthand end portion of the rock shaft 16 differs from the usual release key in having an upper extension or prolongation 18, for purposes hereinafter described. The travel ing carriage comprising the truck 5, 6, 7 and the platen frame 9, 10, is controlled by the usual spring drum and cscapement devices, not shown, and it is to he understood that other necessary mechanism of the Reinington machine, not herein disclosed, is preferably to be employed, although of course the invention may be readily adapted to other existing styles of writing machines.

In carrying out one form of the invention, I provide upright side arms or bracket members 19 having hubs 20 and 21 which extend inward from the side arms. The hubs fit over the cross bar 10, which is fixed to the end bars 9 by screws 22. The hubs 21 receive set screws 23, which secure the bracket arms 19 to said bar 10. The hubs 20 fit loosely over the rock shaft 16 so that said shaft may be turned or operated by the release key 17, 18. The construction is such that the bracket arms 19 are held in fixed relationship to the platen frame near the end bars 9, the bracket arms or supports 19, together with collating devices carried thereby, participating in the up and down case shifting movements of the platen and platen carrier on the carriage truck as this is found to be a desirable construction, although of course the collating devices may have a non-shifting support. The bracket arms or side bars 19, while preferably made detachable in some manner, such as that described, may of course be formed integral with the side bars 9 of the platen frame. In either case the two-part collating contrivance presently'to be described may properly be said to be connected to the carriage of the machine. Pivoted at- 24 to the upper end of each bracket arm 19 isan upper link or arm 25, the lower portion of each bracket arm 19 pivotally supporting at 26 one of a pair of lower arms or links 27. The two pairs of arms and 27 constitute a parallel linkage system which carries a two-part paper holder or collating contrivance, one part being rotatably supported by the other so that the flat paper receiving plate or collating board may be reversed following each collating operation, said board being adapted to collate sheets on both of its faces The supporting part of said paper holder or con trivance comprises a pair of upright arms 28 which are carried by the outer or free ends of the set of links. 25 and 27 and are connected through the collating board itself. Each arm 28 is pivot-allyconnected at 29 to one of the upper links 25, the lower links 27 supporting the lower ends of the arms 28 through pivotal connections 30. Normally the set of links is horizontally disposed, as in Figs. 1 and 3, and at such times the arms 28 are parallel with and forward of the brackets 19 and disposed above the platen towards its rear side. The arms 28 are maintained in this normal position in any suitable way, as by a stop pin or pins 31 projecting outwardly from the links 25, the pins 31 resting on stop faces 32 on the arms 19. As hereinafter explained, the links 25 are designed to be swung vertically to carry the collating contrivance to abnormal position; and to maintain said contrivance in such abnormal position, locking spring tongues 33 are employed, which spring tongues are arranged on the tops of the arms 19 and are provided with angular extensions 34 which are secured to the arms 19, as by screws 35.

'28 from spreading.

wearer The spring tongues 33 are formed near their free ends with seats or depressions which receive the pins 31 and co-operate with them to lock or maintain the links and the collating contrivance in abnormal position. Said contrivance comprises in addition to the arms 28 a paper holder proper in the form of a flat collating board or plate 36 made of any suitable material, said board being properly faced to receive collated sheets on its opposite faces. The term collating board is herein employed in the sense in which said term has come to be used in connection with typewriting machines, and does not of course refer to the material of which the part or board 36 is made, which material may be metal, wood or some composition, or whatever else may be found suitable. The pivotal connections between the board 36 and the arms 28 are clearly illustrated in lFigs. 4 and 5. Said connections comprise shouldered pivots or devices 37 formed at their outer ends with heads or flanges 38 and 39 which fit rotatively in bearing openings in the arms 28, said arms and the pivot parts 37 constituting supporting devices for the collating board and also a tie or connection between the arms 28 through the board, the heads of the devices 37 preventing the arms pivotal devices 37 are slotted as indicated at 40, to provide cut-outs in which the side edge portions of the board 36 are received, the board and pivot devices 37 being secured together by shouldered screws 41. A. collar 42, secured by a cross pin 43 to the right-hand device 37 inside the arm 28, prevents outward displacement of the device, the construction allowing the device to turn freely in its bearing in the righthand arm 28. Arranged on the left-hand pivot device 37 inside the arm 28 is a wheel 44 provided with ratchet teeth 45, the ratchet wheel having a hub 46 which is pinned or. otherwise secured to the'supporting pivot device 37 and thus maintains the ratchet wheel in fixed relationship with the collating board 36. Said ratchet wheel co-operates with the inner face of the arm 28 to prevent outward or leftward displacement of the pivot 37 and the board 36. A spring detent device comprising a roll 47 carried by the free end of a spring arm 48, which is secured by a screw 49 to the left-hand arm 28, co-opcrates with the ratchet wheel 44, the roll 47 engaging with the teeth at the front side of the ratchet wheel to cause frictional resistance designed to prevent accidental turning movement of the ratchet wheel and collating board. Engaging with the ratchet wheel at its top is a pawl member 50 which is pivoted at 51 to the arm 28, the pawl being provided with a finger piece 52 and adapted to contact with a stop pin 53. From Fig. 1 it will be apparent that the pawl will The inner ends of the l prevent rotation of the collating plate in one direction, but the finger piece 52 may be depressed so that the board will be free to rotate in either direction except for the friction due to the detent roll 47 or the pawl may be left off if desired as when it is preferred instead of continually turning the board in one direction, to turn it backward and forward during the course of the work.

Paper controlling means or devices are provided for co-operation with the board or plate 36, there being two sets of such devices, one set co-operating with one face of the board and the other set with the opposite face thereof. These paper controlling devices may be of any construction which is found suitable or desirable for the work in hand. For purposes of illustration I have shown each set as comprising a plurality of pressure rolls 54 arranged in a vertical line, there being three rolls in each set. Each roll is pivotally mounted on an angular arm 55, being received in a cut-out indicated at 56 in said arm. The arms of each set are fixed to a rock shaft 57 which bears in brackets 58 secured to the face of the board 33 near its left-hand edge. Each shaft 57 carries a coiled spring 59 which tends constantly to press the rolls 54 into engagement with the board or the work sheets thereon. The upper arm of each set may be provided with an outwardly extending finger piece 55 which may be depressed to rock the shaft 57, overcoming the spring 59 and throwing the rolls well upward out of contact with the collating board or holder. Also there may be associated with each set of rolls 54 a side gage consisting of a sheet metal angle bar suitably secured to the board 36. From Fig. 3 it will be ob served that the rolls 54 of each set are disposed one above the other and that the set as a whole is arranged somewhat nearer the lower edge of the front face of the board than to the top edge. For the sake of clearness the supports for the rear set of rolls 54 are omitted from Fig. 3, only the rolls themselves being shown in dotted lines. be understood thatsthe two sets of rolls are preferably arrange in the same fore and aft plane at opposite faces of the board and near its left-hand edge,'but that the disposition of the rolls is such that the set at the front is always nearer the lower edge of the board than the top edge.

For some classes of work it maybe preferred to release the feed rollers 13 and 14 automatically, and, to this end, the left-hand arm or link 27 is formed With a lateral extension or finger 61 which is adapted to cooperate with the extension 18 to cam the release arm or key 17 rearward to release the said rollers. The feed rollers however may be released by hand at any time, as is usual by actuating the key 17, and of course the It willautomatic release may be dispensed with when unnecessary or not desired.

With the parts in normal position, as in Figs. 1 and 3, it will be observed that the flat paper holder or collating board 36 is substantially upright, that it is in rear of the platen, and that its'lower end is well within the bight formed by the rear face of the platen, the pressure or feed rollers 13 and the apron or deflector 15. With the board in this position it willbe understood that the collated sheets are led or fed from the back face of the board. passing downward from the rear set of rolls 54 into the control of the platen and main and secondary feed rollers 13 and 14, and thence to the front side of the platen into position for receiving impressions at the front printing face thereof from the type bars 12. The sheets are first collated at the front face of the board and in order to obtain room to position the board for collating operations, a relative separation is efiected between it and the platen and printing instrumentalities. For this purpose, the board is moved first to the abnormal position illustrated in full lines in Fig. 2 where it is separated or spaced away from the platen, considered both rearwardly and upwardly. This of course is effected by a relative separation of the platen and the two-part paper holder; that is. by swinging up the pairs of links 25 and 27 from the horizontal position of Fig. 1 to the vertical position of Fig. 2, such movement carrying upward the arms 28 and the board 36, the linkage providing guiding means to cause what is usually termed parallel motion of the parts, so that in the Fig. 2 position the board is still upright as in Fig. 1, although it has been moved rearward and lifted to withdraw it from the bight at the rear of the platen. Thus positioned, the board is free to be turned on its pivots without obstruction from the platen or other parts, which of course was not the case in the 'Fig. 1 position. In moving from the Fig, 1 to the Fig. 2 position it will be observed that the finger 61, acting as a cam on the arm 18, has automatically released the feed rollers 13 and 14. With the collating contrivance as a whole in the Fig. 2 position the collating board 36 may beturned or rotated on its pivots 37 in the direction of the arrow in Fig. 2 until the board has been brought to any convenient angular position such as that illustrated by the dotted lines in Fig. 2, thus effecting a relative movement between the two parts of the paper holder, viz, the board 36 itself and the frame comprising the arms 28. The detent 47 will co-operate with the ratchet wheel to assist, in maintaining the board in this position and the pawl 50 will positively prevent return rotation of the board and will enable the operator to press against the forwardly .43 has extending portion of the board during collating operations without disturbing the angular position of the board. With the board in inclined or partly turned position as shown by the dotted lines, the operator may then release the front set of pressure rolls 54 and readily assemble or adjust the work sheets in collateral relationship against the side guide 60.

. is somewhat shorter and also narrower than the record sheet 62, the latter being intended to receive duplicate impressions through an interleaved carbon. In the present instance the operator having thrown off the front set of rolls 54,*and collated the sheets, it has been assumed that the upper portions of both sheets will extend above the top edge of the collating; board, one sheet somewhat further than the other. The sheets having been collated the rolls 54 are restored and co-operate with the board 36 to hold or maintain the sheets in collated position. Thereafter the rotation of the board is.continned in the direction of the arrow, Fig. 2, until the board has been completely reversed or turned to a vertical position with the collated sheets at the rear side thereof and the projecting top portions of said sheets now extending downward past what is now the lower edge or end of the board. The ends it will be noted have been changed, the former top being now the bottom. Thereupon the two-part collating contriv ance is swung bodily, or as a whole, forward and downward through forward rotation of the linkage system 25. 27, until arrested by cont-act of the stop devices 31 and 32. At the latter part of this movement the feed rolls 13, 14 will be automatically released by the finger 61 and restored to operative position by the usual springs engaging with the advance portions of the collated sheets and operating to feed them in co-operation with the platen around the latter and off the rear face of the board 54.

A modification of the Figs. 1-5 construction above described is illustrated in Fig. 6 wherein the arms 28 are replaced by arms 65 having forward extensions 66 formed with horizontal slots 67, terminating at the rear in depressions or seats 68 and at the front in like depressions or seats 69. The slots 67 receive the pivots 37 of the collating board 36, said pivots normally being seated in the depressions 68 at the rear of said slots.

-When, however, the collating contrivance ease has been swung upward to the abnormal position corresponding to that shown in Fig. 2, the board 36 may be moved or pulled forward bodily, the ivots 37 traversing the slots 67 until said pivots seat in the front depressions 69. The left-hand extension 66 may carry a pawl member 70 which will at this time engage with the ratchet wheel 44, enabling the board 36 to be now rotated on its pivots to an inclined position and held as before during the collation of the sheets, after which the reversal of the board may be completed and the parts, after the board has been pushed or slid rearward along the slots.67 until the pivots 37 seat in the de re'ssions 68, restored to normal position as eforc. The Fig. 6 construction may be employed in cases where it is preferred to bring the collating board nearer the front of the machine and closer to the operator during collating operations than the first construction admits of. It will be noted that pawl and ratchet devices co-operate with the board in both positions to which it may be slid in the slotways 67.

One of the common classes or styles of collating work involving assemblage of work sheets in variable relationships, includes the employment of an inner record sheet in the form of a loose leaf ledger sheet and an outer sheet in the form of a narrower and shorter monthlyl statement sheet which may be ositioned at any point lenthwise of the journal sheet, depending on the number of prior entries. To take care of this style of collating work the form of the invention shown in Figs. 7 to 12 may be employed. This construction differs from the Figs. 1 to 5 construction in providing a clamping device which is mounted on the collating board in such a way that it may be moved relatively thereto to any location on either face of the board in order conveniently to position such device for clamping the collated sheets, said clamping device thereafter being movable as desired to continuously advance the collated sheets down over the collating board and around the platen until the first writing line has been brought opposite the printing point. In the Figs. ,7 to 12 construction, the brackets or side arms 19, as before, movably support, through the pairs of parallel links 25 and 27, a paperholder or collating 'contrivance comprising the parallel upright or vertically disposed arms 28 which provide bearings for the pivots 37, slotted as before to receive the collating plate or board and fix it in place by the screws 41. The linkage system 25, 27, as in the prior construction, provides means for affording relative separation between the collating contrivance and the platen and printing instrumentalities, and the pivotal devices 37 are camprised as before in means which afford relallll tive movement between the collating board support and the board itself. The collating board 86 of the first described construction is however in the present instance replaced by a collating plate or board 71 which is pivotally supported on the arms 28 at 37 as is the board in the first described construction. The collating board 71, however, is provided at its upper and lower edges with rotary bearings'for clamp carrying and paper feeding bands. These rotary bearings are in the form of flanged rollers or spools 72 which are pivoted on brackets numbered as a whole 7 3, and best disclosed in Fig. 12. Said brackets may be formed of sheet metal and comprise angular ears 74 and a cross connection 75, the ears being slotted at 76 and perforated at 77, the perforations providingbearings for the rollers 72, and the slots 76 enabling the brackets 7 8 to be fitted over the edges of the board 71 near its side edges and secured as by rivets 78. Passing over the rollers are flexible endless bands 79 which may be of very thin metal or other suitable material, said bands being adapted to turn or advance continuously in either, directi'on on their bearings 72 and relatively to the board 71 near the side edges whereof they are disposed, it being understood that the bands loosely enclose or embrace the board, as best appears in Fig.7.. The endless bands 79 provide a support or carrier for a clamping device which in the present instance may comprise essentially two parts or bars 80 and 81, said bars being horizontally arranged, extending transversely of the collating board and providing a connection between the two endless bands 79. The clamping bar or device 80 .is secured near its opposite ends directly to the bands, as by rivets 82, the construction being clearly shown in Figs. 9 and 10. The bar 81 is hinged at 83 at its left-hand end to the bar 80 (or as viewed from the rear, as

in Fig. 8, to its right-hand end), so that.

the bar 81 may be swung away from the bar 80 to open the clamp. Means are provided for latching th bars together in operative or clamping relationship, said means comprising an arm or latch 84 pivoted at 85 to the right-hand portion of the bar 80 which extends beyond the adjacent band 79. The inner end of the latch 84 is adapted to co-operate with the free end or tongue 81* of the arm'.81.and to hold the arm under tension against an inherent tendency to spring away from the bar 80. The latched engagement of the parts is clearly illustrated in Fig. 9. It will be understood that by turning the latch 84 on its pivot it is caused to release the tongue 81", thus freeing the bar 81 and unclamping the work sheets which may be confined or held between'the two clamping bars. If desired the unlatching may be elfected automatically and in the present instance l have illustrated this operation as being accomplished by the en gagement of the outer end of the right-hand end latch 84: with the top edge of an angular leaved carbon sheet. The sheets are desig-- nated in the present instance by the numbers 86, 87 and 88, the number 86 referring to the record sheet, 87 to the statement sheet, and 88 to the carbon sheet.

In operation, the collating contrivance is moved bodily from the normal position in Fig. 7 upward and backward to the abnormal position, thus effecting relative separation between :the platen and printing 1nstrumentalities on the one hand and the collating or assembling contrivance on the t othe r,'through the upward swing or rotation of the means or linkage system 25, 27.

Thereafter the two-part clamp 80, 81 is brought to the front face of the collating board by a feeding or advance movement of the endless band 79 in either direction. For convenience in moving, bands, lateral extending finger pieces 89 may be applied to them, and the clamp itself may also be used conveniently for this purpose. After the clamp has been brought to the desired position at the front face of the collating board it may be opened, the part 81 being swung outward and to .one side. The board 71 may of course be tilted to or set in any desired or convenient angle through means comprising the devices 37 in order to facilitate the collation of the sheets. The sheets are laid on the board andassembled or collated against the clamping bar 80 being pushed towards the right against lugs 80 which are struck up from said clamping bar and serve as side edge guides for the sheets. Thereafter the clamping bar 81 is swung down and latched in place by hand, thus securing the collated or assembled sheets in desired relationship against the face of the board 71. The board may now be further rotated on its pivots 37 to complete its reversal, thus bringing the clamp' 80, 81 to the back of the -.board. Next the board may be restored from normal to abnormal position by pulling it forward and causing the links 25, 27 to swing downward and forward, after which the clamp may be moved down behind the board or feeding the by longitudinal feeding movements comrollers are disenga ed from the platen, so that the collated sieets may be advanced continuously over the platen by the clamp until they have been brought into position to receive the first line of writing at the front of the platen. Thereafter the feed rollers are restored into co-operative engagement with the platen to hold the collated sheets, and the clamp may then be unlatched by rotating the pivoted latching device 84 to release the tongue 81. This unlatching will ordinarily be eifected by hand, but in some classes of work it may be found as stated that an automatic releasing of the clamp is desirable in which event the finger 84: or a similar device may be employed to automatically unlatch the clampin bar 81 as it is advanced or fed downward behind the collating board 71. Or the release arm maybe given a slight lost motion at the conclusion of its return stroke and furnished with a device or finger to act against or cam the latch arm 84 and swing it out of operation. It will be understood that the Figs. 7-12 construction enables the sheets to be collated in any desired relationship and advanced while held positively in this relationship to the printing point on the platen before the sheets are released from the clamp 80, 81. It is apparent that after the collated sheets are brought within the control of the platen and its pressure rolls, and the clamp has been rendered inoperative, the collated sheets may be advanced or fed over the platen by actuating the usual line spacing devices.

Besides those described various other modifications, and changes within the principles of my invention will suggest themselves to those skilled in the art.
